Description of Related Art

[0003] Food waste is one of the great scourges in the food industry today. The food waste knows several definitions according to the country. For example, in the first directive of 1975 in Europe 75/4423/EEC, the food waste is defined as “any food substance raw or cocked which is thrown away, intended to be thrown away or needs to be thrown away”. In the USA, a same definition exists at a federal level and even in the FAO (Food and Agriculture Organization of the United Nations). A study from the FAO estimated the global food waste to be close to 1 .3 billion tons of food lost or thrown away each year.

[0004] Consequently, food waste is a global societal, social, environmental, economic and even health problem. Indeed, the food waste leads to financial losses for producers, retailers, and consumers. For example, in the UK, in 2009, it represented almost 530 euros per household each year (FAO). Another example, a study made for the European Commission on food waste, avoidable or unavoidable, concludes that 140 kg/inhabitant is wasted. In France, according to the ADEME (Agency for the Environment and Energy Management), the cost of food waste is estimated to be between 100 and 160 euros per year and per person, or a bill of 12 to 20 billion euros.

[0005] Moreover, the food waste leads also to water and energy loses and even more the increase of greenhouse gases.

[0006] In order to reduce this food waste, many legislations are being put in place across different countries and organizations. In France, the state adopts the European Parliament's commitment to halve waste by 2025. [0007] A study in France conducted by ADEME estimated vegetables as most wasted (31 %), followed by liquids (24%) and baked products (13%) and in particular 10% of baked bread is thrown away.

[0008] At least a part of the wasted baked product can be associated to a short shelf-life, between 1 and 6 days.

[0009] To improve the shelf-life of baked goods and reduce the food waste, bakers and bakery industry are using several additives during breadmaking. For example, to prevent mold appearance, bakers can use artificial or natural preservatives. Depending on their action, the use of these additives faces to different but often common problems: increasing of off-tastes and off-flavors, acidification, impairment of yeast growth, rheological issues, increasing of sugar contents and the incompatibility with a clean label for most of the artificial additives.

[0010] Moreover, a large part of artificial and natural additives is based on an acidifying action, e.g. organic artificial acids that act as antimicrobials (benzoates, sorbate, propionate for example) and natural acid agents (vinegar, citric acid, fruit juices or concentrated) Claudia Axel, Emanuele Zannini & Elke K. Arendt. Mold spoilage of bread and its biopreservation: A review of current strategies for bread shelflife extension. Critical Reviews in Food Science and Nutrition. 2017). Among the natural mold inhibitors that would lead to an acidification of the recipe, the use of products based on fermented wheat (W02020217247) or whey could also be an option Raul Ricardo Gamba, Candela Moure, Gabriela Diosma, Leda Giannuzzi, Graciela Liliana De Antoni, Angela Marfa Leon Pelaez. Application of Whey Permeate Fermented with Kefir Grains for the Shelf-Life Improvement of Food and Feed.

A natural strategy to improve the shelf life of the loaf bread against toxigenic fungi: The employment of fermented whey powder. International Journal of Dairy Technology.). In this case, fermenting agents are mostly bacteria (lactic acid bacteria (LAB), actinobacteria, bifidobacteria for example) and more rarely yeasts (e.g. Meyerozyma guilliermondii, Pichia anomala) and their production or organic acids can play a role on their anti-mold properties.

[001 1] To improve the shelf-life, other techniques have been developed as the use of enzyme, and in particular complex enzyme mixture comprising a maltogenic amylase, at least one other amylase, phospholipase, protease and lipase from Rhizopus oryzae to increase bread’s shelf life (US6923994). [0012] In addition, it is necessary that the technique be easy to implement for the baking industry as well as for the significantly growing home-made.

[0013] Hence, there is a need for natural solutions capable of increasing the shelf-life of baked products that are easy to implement in industry or in home-made and that reduce food waste as explained above.

Detailed description

[0033] A description of example embodiments of the invention follows.

[0034] In the following description, when a range is used the limits are included unless otherwise specified.

[0035] The term "about" as used herein can allow for a degree of variability in a value or range, for example, within 10%, within 5%, or within 1% of a stated value or of a stated limit of a range.

[0036] The term "substantially" as used herein refers to a majority of, or mostly, as in at least about 50%, 60%, 70%, 80%, 90%, 95%, 96%, 97%, 98%, 99%, 99.5%, 99.9%, 99.99%, or at least about 99.999% or more.

[0037] By “substrate”, it should be understood any composition comprising organic matter or a mix between organic matter and inorganic matter allowing initiating or facilitate a fermentation process, for example it can be a source of glucose, a source of carbon, a source of protein, or more generally a source of nutrients that may comprise carbon, nitrogen, minerals... In addition, a substrate may comprise any plant material. [0038] In particular, the expression “substrate to be fermented”, within the meaning of the invention, can correspond to any substrate suitable for the development of an organism responsible for fermentation process.

[0039] “By-product” generally relates to a product that is produced as a result of making another product. For example, by-products can be produced during the extraction of juice from fruits or vegetables. Pomace is a typical by-product of fruit juice and vegetable (tomato, carrot) production; sugar beet pomace is a by-product of beet sugar production. Peels and seeds are also common by-products of the food industry. Hence by “by-product » it can be understood peels, skins, pulp, seed, pomace, cake, marc, straw, bran, cobs, shells, and kernel of: fruit, vegetable, cereal or pulse.

[0040] By “edible product”, it should be understood any product that is orally taken by animals and/or human beings, in a solid or liquid form, such as flour and products derived from flour, breadmaking products, biscuits, cakes, meat substitutes, dairy products (milk, yogurt, and butter), dairy substitutes, beverages, cooking aid (stock cubes and the like, aroma, emulsifying agent).

[0041] As mentioned, food waste continues to grow and in particular the food waste of baked product. The technics currently used to or developed do not allow to improve the shelf life in a natural and easy way of baked products. There is a need for natural solutions capable of reduce the waste of baked products and that are easy to implement in industry or in home-made.

[0042] According to a first aspect, the invention relates to a method of preparing an edible product. Preferably the invention relates to a method of preparing a baked product.

[0043] In particular, as illustrated in figure 1 , a method 100 of preparing a baked product according to the invention comprises the following steps: mixing 110 grain flour, flour derived from fungal fermentation of plant material, yeast, aqueous composition together to form a baker dough; and applying a heat treatment 120 to the baker dough to make a baked product.

[0044] A method 100 according to the invention can also comprise the following steps: steps of drying, chilling, extruding, kneading, fermentation, shaping and/or flattening, and/or adding ingredients, and/or leavening the baker dough, and/or adding one or more enzymes.

[0045] As shown in figure 1 , a method 100 of preparing a baked product according to the invention comprises a step of mixing 110 to form a baker dough. [0046] This step may be implemented by a device (food processor, mixer, breadmaking machine) and/or manually.

[0047] The step of mixing may be conduct at a temperature between 4°C and 30°C.

[0048] The step of mixing may be conduct within a period between 3 min to 120 min Advantageously, the step of mixing may be implemented uniformly. The step of mixing comprises mixing together grain flour, a flour derived from fungal fermentation of plant material, dry yeast, aqueous composition. The mixing allows to form a baker dough.

[0049] The step of mixing comprises mixing grain flour with the other ingredients. The mixture may comprise at least 20 % in weight of grain flour, preferably at least 25 % in weight more preferably at least 30 % in weight. The mixture may comprise at most 80 % in weight of grain flour, preferably at most 75 % in weight, more preferably at most 70 % in weight. The mixture may comprise between 20 % and 80 % in weight of grain flour, preferably between 25 % and 75 % in weight more preferably between 30 % and 70 % in weight. The grain flour may comprise wheat flour, corn flour, rye flour, barley flour, oat flour, rice flour, sorghum flour and/or a combination thereof. The grain flour allows to participate to the elaboration of the baked product and in particular to the taste, the color, the consistence and texture.

[0050] The step of mixing comprises mixing a flour derived from fungal fermentation (FFF) of plant with other ingredients. The mixture may comprise from 0.25 % to 40.00% in weight of a flour derived from fungal fermentation of plant material. Preferably, the mixture may comprise from 0.40 % to 35.00% in weight of a flour derived from fungal fermentation of plant material, more preferably from 0.60 % to 30.00 % and even more preferably from 0.90 % to 25.00 %.

[0115] EXAMPLES

[0116] Breadmaking.

[0117] Materials

- Air-o-steam oven Electrolux, razorblade, kettle, kitchen aid for kneading, kitchen aid bowls, serviettes, thermometer, 10L bottle and 500 ml bottles, funnel, water spray, marker and tape, kitchen scale, baking paper, cutting board.

[0118] Ingredients

- Wheat flour (T65) : 3.92 kg

Flour derived from fungal fermentation of plant material (FF) o Citrus flour : 40 g o Tuber flour 40 g

- Salt : 72 g

- Yeast (Saf-levure-dry) : 43.5 g

[0119] Recipe for 500 g of wheat flour

[0120] Mix all the ingredients together well until for and homogenic dough, adding water, kneading, resting, shaping, cooking.

[0121] The present invention relates to the use of flours produced from the fermentation of fruit, cereal and vegetable by-products, as described above, in order to extent the shelf-life of baked product and reduce the food waste. The positive effect of these flours to delay the visual detection of the first mold is demonstrated. The effect of these flours to reduce water activity and moisture content play a role on the bread’s shelf life.

[0122] Table 1. Bread shelf-life (visual detection of molds) depending on the flour derived from fungal fermentation of plant material used as an additive and their concentration. The increasing of bread shelf-life is the proportion of the number of days without any visual detection of molds in supplemented breads compared to that in control breads (0% of flour derived from fungal fermentation of plant material). The asterisk indicates a ratio on which the number of days before the visual detection of molds is significantly different between control and supplemented breads, according to a t-test (p-value < 0.05).

[0123] In one embodiment, the visual detection is significantly delayed in time when the flour derived from fungal fermentation of plant material is added to the recipe (Table 1 ). Breads can stay maximum 40% days more compared to a control without the visual detection of a mold. The original recipe contains 60% of water, 1.8% of salt and 1.25% of dry yeast compared to wheat flour (T65). The flour derived from fungal fermentation of plant material is added in replacement of wheat flour. When flour derived from fungal fermentation of plant material is added at 5%, more water needs to be added. Also, the recipe for flour derived from fungal fermentation of plant material and for example orange flour at 5% contains 80% of water compared to wheat flour (76% compared to total flours) and the recipe for flour derived from fungal fermentation of plant material with beetroot for example at 5% contains 75% of water compared to wheat flour (73% compared to total flours).

[0124] In an aspect, the delay of the first mold visual detection is observed if the breads were prepared handmade and if there were prepared using a food processor as well.

[0125] In another aspect, the delay of the first mold visual detection is observed from ratios of flour derived from fungal fermentation of plant material / Wheat flour ranging from 1 % to 5%. [0126] In another aspect, the delay of the first mold visual detection depends on the fruit or vegetable by-product. If the maximum delay induced by orange flour is close to that by beetroot flour (+40% of days and +38% of days, respectively), the effect is already observable if the beetroot flour is formulated at only 1% compared to the wheat flour while it requires 2% of orange flour in the recipe to observe the effect.

[0127] In another aspect, the mold development is also longer in breads supplemented with orange and beetroot flours (figure 1 ).

[0128] Table 2. Properties of handmade breads prepared with or without beetroot flour, regarding their water content. Different letters (a, b) indicate significantly different values for a same column according to a t-test (p-value < 0.05).

[0129] Table 3. Properties of breads prepared with a food processor and with or without orange GST flour, regarding their water content. Different letters (a, b) indicate significantly different values for a same column according to a t-test (p-value < 0.05). [0130] In another aspect, the delay of the first mold visual detection can be related to a decrease of water activity and relative humidity of breads, like with the use of beetroot flour (table 2) but can also be related to other factors if these two parameters are not different to that of a control, like with the use of orange flour (table 3).

[0131] In another embodiment, the use of flour derived from fungal fermentation of plant material in a bread’s recipe could reduce the water activity and the moisture content of final baked goods, like it is observed with the use of beetroot flour (Table 2). The original recipe contains 60% of water, 1 .8% of salt and 1 .25% of dry yeast compared to wheat flour (T65). The flour derived from fungal fermentation of plant material is added in replacement of wheat flour. When flour derived from fungal fermentation of plant material is added at 5%, more water needs to be added. Also, the recipe with orange flour derived from fungal fermentation of plant material at 5% contains 80% of water compared to wheat flour (76% compared to total flours) and the recipe for beetroot flour derived from fungal fermentation of plant material at 5% contains 75% of water compared to wheat flour (73% compared to total flours). The use of flour derived from fungal fermentation of plant material at a level of 1% or 2% compared to the wheat flour helped to significantly reduce the water activity and the relative humidity in breads.

[0132] In an aspect, the reduction of water activity and relative humidity in breads by the use of a flour derived from fungal fermentation of plant material in the recipe was observed directly after the breadmaking and still observed after 3 days of storage.

[0133] In another aspect, the reduction of water activity and relative humidity in breads by the use of a flour derived from fungal fermentation of plant material in the recipe was more persistent if the flour derived from fungal fermentation of plant material was added at a level of 2% compared to the wheat flour.

[0134] In another aspect, the reduction of water activity and relative humidity in breads by the use of a flour derived from fungal fermentation of plant material depends on the fruit or vegetable by-product used to prepare the flour derived from fungal fermentation of plant material. If this effect was observed with beetroot flour (table 2), it was not observed with orange flour (table 3).

[0151] Visual - Brioche Sandwich bread - First appearance of mold (D = days)

[0152] Thanks to the presence of the flour derived from fungal fermentation of plant material the shelf-life of the tests are increased in comparison with the control. The control was mostly after 21 days while those prepared with flour derived from fungal fermentation of plant material was not.

[0153] The present invention can be used in baked good formulations, from a concentration ranging from 1% to 5% compared to wheat flour, in order to increase their shelf-life by reducing the mold contaminations. The invention can also replace artificial or natural additives already commercialized to this end.

[0154] The presence of a flour derived from fungal fermentation of plant material allows to increase the shelf-life of a baked product. The invention allows to demonstrate that the addition of flour fermented from fungal fermentation makes it possible to reduce the appearance of mold.

[0155] Surprisingly, the Applicant has demonstrated that the use of flour derived from fungal fermentation based on fruit, vegetables or cereals makes it possible to reduce the appearance of molds in bakery products. Indeed, the same results (increase the shelf-life in comparison with the control) are obtained for flour derived from fungal fermentation from fruit or from vegetable or from cereal.

[0156] In addition, just as surprisingly, the Applicant has demonstrated that a strain of fungus is not preferred. Indeed, the presence of flour fermented from fungal fermentation reduces the appearance of mold.

[0157] The tests were carried out with strains from Aspergillus and Pleurotus. However, the same result are obtained with Fusarium, Hericium, Pleurotus, Aspergillus, Rhizopus, Morchella, Monascus and/or a combination of thereof,.

[0158] Thus, the antifungal effect depends on the presence of the flour derived from fungal fermentation in the preparation, (ie. any fruit/vegetable/cereal material fermented with any strain but preferably with Fusarium, Hericium, Pleurotus, Aspergillus, Rhizopus, Morchella, Monascus and/or a combination of thereof).

[0159] Indeed, whatever the type of material (fruit and/or vegetable and/or cereal), the effects of reducing the appearance of mold are observed. Similarly, regardless of the type of strain, the effects of reducing the appearance of molds are observed.

[0160] The invention can be the subject of numerous variants and applications other than those described above. In particular, unless otherwise indicated, the different structural and functional characteristics of each of the implementations described above should not be considered as combined and / or closely and / or inextricably linked to each other, but on the contrary as simple juxtapositions. In addition, the structural and / or functional characteristics of the various embodiments described above may be the subject in whole or in part of any different juxtaposition or any different combination.
